I studied Lustre last week a little bit and, talking about MDSs and
OSSs, I came with one reason for them not to make Lustre to support
Gentoo: Lustre uses a lot of kernel features that if not enabled will
cause the kernel to crash.
I didn't find any documentation explaning those features but I could
make a list of the orbivious ones: LVM, DM, ext3, ...
I think that even they can't make a list of all those features, that
is why they have to make Lustre available mainly on pre-compiled /
pre-configured kernels. And, thank God, Gentoo doesn't have a
predefined kernel. Although that would make easy for them to change
and distribute it.
What do you think about my ideia?
It really shouldn't be that difficult to add in features until it stops
crashing, then specify those features as dependencies in the kernel
build system.
But that leads to a more generic question: if Linux is always Linux
(the kernel), and the distro is only a way to organize packages, files
and init scripts, why would anyone need restrict an open source
software to a distro? If my first assumption is right, the quicky (but
not necessarily well thought) answer would be: lack of knowledge.
Sure. If they offer to support Lustre on a distribution, they need to be
able to fix problems on that distribution. That means being aware of
possible distribution-specific interactions that could cause issues and
also knowing how to deal with them as well as reproduce them locally.
Thanks,
Donnie
